The Heavy Links between Geological Events and Vascular Plants Evolution: A Brief Outline

Area of Science:

• Paleobotany
• Geology
• Evolutionary Biology

Background:

• Life, originating with photosynthesis, profoundly altered Earth's atmosphere (O2, CO2) and geochemistry.
• Vascular plants, evolving from early life forms, transformed terrestrial landscapes, geological cycles, and elemental cycles.

Purpose of the Study:

• To determine the origin and diversification of vascular plants.
• To analyze the influence of geological history on plant evolution using a novel computational approach.

Main Methods:

• Bayesian analysis of the fossil record from the Silurian period to the present.
• Utilizing new software, PyRate, to calculate plant origination and extinction rates.
• Comparing PyRate-derived data with geological event timelines.

Main Results:

• Vascular plant evolution was significantly influenced by geological events.
• The rise of nonflowering seed plants and the rapid spread of flowering plants correlate with geological-induced environmental changes.
• PyRate software successfully modeled plant diversification rates against geological history.

Conclusions:

• Geological phenomena have been a primary driver of vascular plant evolution.
• Environmental shifts caused by geological events explain key plant diversification events, such as the spread of flowering plants.
• The interplay between geology and plant life is a critical factor in Earth's biological and geological history.
